Mosques are Muslim places of worship and prayer. The word "mosque" comes from the Arabic masjid, which is related to the word for "prostration." Muslims are expected to pray five times a day, preferrably in a mosque: morning, midday, afternoon, sunset, and evening. A muezzin calls the worshippers to prayer from a minaret (Arabic manara, a tower). Included in our index are some Islamic places of worship that are not technically mosques, such as the Dome of the Rock in Jerusalem (a Muslim shrine) and the Mezquita de Cordoba (now a cathedral).
